Be it known that we, lrlsnnv E. Buckner ar d P. MALLORY,'l)Ctl1 citizens of the United States, residing at hiladelphia, county of hiladelphia, State of Pennsylvania, have invented a certain new and use tul Improvement in Quantifying Mechanisms, of which the following is a specification, reference being had therein to the accompanying drawings.

This is invention has for an object to provide quantifying mechanism, applicable to substantially any machine which operates in repeated cycles to produce a succession of articles whose number is proportional to the number of cycles of operation of the machine, which quantifying mechanism will operate to control the delivery oit said articles as they are produced in such a manner that after the completion of a predetermined number of eye of operation of the ma chine, and the consequent production of a proportional number of articles, the point of delivery of said articles will be automatically changed, so that said articles will be delivcred from the machine in quantities of a predetermined number each.

More specifically, the invention relates to counting mechanism for die presses so constructed and connected with the operating mechanism of the press that, while the press operates continuously, the articles formed thereby will be removed from the dies and segregated into separate batches each of which includes a given number of articles which may be directly packed for shipment without further counting.

The foregoing and other objects of the invention, together with means whereby the same may be carried into ettech'will best be understood fromthe following description of one form or embodiment thereof illustrated in the accompanying drawings, in which:

Fig. 1 is a side elevation of a die press having my invention applied thereto.

Fig. 2 is a rear elevation of the press shown in Fig. 1.

Fig. 3 is a plan view of the discharge end of the chute by means of which the articles formed by the press are delivered, said figure illustrating the operation of the switch gate at the delivery end of said chute.

The drawings show the invention as ap- H (in Serial No. 551,494.

from any suitable source through a beltpulley 15, said shaft having a crank portion 16 connected by a pitman 17 with a reciprocating ram 18 guided in the frame 10 and carrying the upper or movable die 19. The number of articles formed by the press; in any given time will be equal or proportional to the number of strokes of the ram 18 during the same period, depending upon the nature of the dies 13 and 19. Inthe machine shown, said dies are preferably of the double type shown and described in Letters Patent No. 1,378,707, granted May 17, 1921, to George'P. Mallory, whereby two spoons are produced at each stroke of the ram 18.

Also, in the construction shown, the spoons or other articles are blown from between the dies, when the latter are separated, by a blast of air supplied by a suitably arranged pipe 20, said articles passing into and through a delivery chute 21 supported by the frame 10 at the back of the machine. The articles are delivered by the chute 21 into baskets or other receptacles 22 suitably supported, as by a bench 23, at the delivery end of said chute.

The chute 21 is provided with a switch whereby the articles passing therethrough may be diverted into any one of a plurality of receptacles 22. As shown most clearly in Figure 8, said switch comprises a gate 24; pivoted adjacent the delivery end of the chute 21 centrally ot the latter, said gate being movable on its pivot'either into the position A shown in full lines inFigure 3, or into the position B shown in dotted lines therein. It will be seen that with the gate 2a in the position A, the articles passing through the chute 21 will be diverted toward one side of the latter, as indicatedby the arrows, and'may be received in a suitably disposed receptacle 22, but that it said gate be moved from the position A'into the position B the delivery ofthe articles intothe receptacle 22 will be discontinued and said articles diverted toward the opposite side of the chute where they may be received in a second receptacle 22 7 Secured at one end to the gate is a spring 25 the opposite end of which may be engaged with or attached to either one of two keepers or hooks 26 and 26" carried by opposite ends of a bar 2? extending transversely of the chute and supported by rods 31 secured to the frame 10. It will be seen that when the spring 25 is engaged with the hook 26 said spring will tend to swing the gate 24 from the position A intothe position B, and that when said spring is engaged with the hook 26" it will tend to swing said gate from the position B into the position A. The gate 24 is locked against movement in either the position A or the position B by one or the other of two detents 28 and 28", respectively, carried by a rock shaft 29 extending transversely of the chute and journalled in brackets 30 carried thereby. The rock shaft 29 has fast upon one end an arm 32 connected by a spring 33 with one of a pair of uprights 34-ca-rried by a bracket 39 secured to one side of the frame 10. The spring 33 normally holds the end of the arm 32 in engagement with the face of a master wheel 35 journalled in said uprights 34, said arm when in this position niiaintaining the rock shaft 29 in an angular position wherein the appropriate detent 28 or 28 is in looking engagement with the gate 24. The arm 32 is periodically e.ugaged, during the rotation of the master wheel 35, by one or more trips in the form of pins 36 carried by said wheel, engagement of said arm by one of said trip pins serving to rock the shaft 29, thereby lifting the det-ents 28 and 28 and releasing the gate. The master wheel 35 has formed about its periphery the teeth of a worm gear with which meshes a worm 37 carried by .a shaft 38 journalled in hearings on the bracket 39. Secured tothe outer end of the shaft 38 is a relatively large sprocket wheel 40 which is connected by a chain 41 with a relatively small sprocket wheel 42 on the outer end of the drawing shaft 14 of the press.

- In operation, the gate 24 is normally locked in one position, for example, the position A, by the corresponding detent 28 so as to divert the spoons or other articles passing through the chute into the basket or receptacle 22, the spring 25 being connected with the hook 26, so as to tend to move said gate into the position B when released by the detent 28. After the press has made a predetermined number of strokes, one of the trip pins 36 engages the arm 32, thereby rocking the shaft 29. lifting the detent 28 and permitting the spring 25 to throw the gate 24 into the position 13. The delivery of articles into the basket 22 will thereupon be discontinued, and said articles will be diverted into the basket 22 As soon as the trip pin 36 has disengaged the arm 32, the detent. 23 will engage the gate 24 to lock the same in the'position B, whereupon the spring 25 is manually disengaged from the hook 26 and engaged with the hook 263*, and the basket removed and an empty basket pu in its place. The mechanism is now in a position to repeat the foregoing operations upon the completion of a predetermined number of strokes of the press, the gate 24, however, making its next movement from the position 13 to the position A.

The gearing connecting the shaftlst with the master wheel 35 may be so designed, and the trip pins 36 so arranged on said master wheel, as to cause the foregoing op erations to take place after any desired number of operations of the mechanism actuated by the shaft 14, and therefore after the passage of any desired number of articles into each receptacle 22, since the number of said articles is proportional to the number of operations or cycles of the mechanism in question. Thus, the master wheel 35 may be arranged to make one complete rotation for each 100 rotations of the shaft 14, and consequently for every 100 operations or cycles of the machine. In the particular application of the invention shown, the dies 13, 19 are, as above stated, adapted to form two spoons at each stroke of the press, so that, at the end of each complete rotation of the master wheel 35, 200 spoons will have been formed. The master wheel 35 may, therefore be provided with two trip pins 36 spaced 180 from each other, so that the mechanism will operate once for every 50 strokes of the press, thereby providing for the delivery of 100 spoons into each res ceptacle 22. The trippins 36 may be so secured to the master wheel 35 as to permit their adjustment thereon, their removal therefrom, or the attachment of additional pins thereto. so as to provide for a variation in the number of articles delivered into any one receptacle. For example, said wheel may have about its edge a series of holes 43 to receive removable pins, so that, said pins may be so set as to cause the mechanism to deliver the spoons in batches of 200, 100, 50, 20, or any other number within the range of adjustment of the mechanism as designed.

It will be abvious that the quantifying mechanism above described is by no means limited to use in connection with the particular machine shown, but that it is equally applicable to any mechanism which is successively operable to form, either wholly or in part, a succession of articles.
